摘要
对空气预热器低温腐蚀进行详细分析 ,找出空气预热器发生堵灰的根本原因在于烟气中存在SO3以及受热面金属壁温低于烟气露点。对此 ,提出了提高受热面壁温在烟气露点以上等控制措施 。
Detailed analysis of low temperature corrosion in regenerative air heaters had been carried out, it was found that the basic causes leading to ash-clogging in the said air heaters were: (1) SO 3 existing in the flue gas; (2) the wall temperature of heating surface was lower than dew point of the flue gas. For these reasions, some control measures for enhancing wall temperature of the heating surface were put forward, so as to ensure the normal operation of the said air heaters.
